The exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.
The first exemplary embodiment of the present invention will be described first with reference to
The mobile terminal device 101 is, for example, a general cellular phone that is currently commercially available, and includes a rechargeable battery 102 formed from a secondary battery such as a well-known lithium ion battery. Although not illustrated, the mobile terminal device 101 also includes an antenna, a transmitting/receiving unit, a main control unit, an operation unit, a storage unit, and a display unit, and is connectable to various kinds of networks.
The mobile terminal device 101 also includes a charger identification information reception unit 103 that receives charger identification information to be used to identify the charger 121 from the charger 121 connected to charge the rechargeable battery 102. The mobile terminal device 101 also includes a setting information storage unit 104 that stores setting information associated with the charger identification information. The mobile terminal device 101 also includes a setting information extraction unit 105 that extracts, from the setting information storage unit 104, the setting information corresponding to the charger identification information received by the charger identification information reception unit 103. The mobile terminal device 101 also includes a setting unit 106 that sets, in the mobile terminal device 101, the setting information extracted by the setting information extraction unit 105.
On the other hand, the charger 121 includes a charger identification information sending unit 122 that sends the charger identification information to be used to identify the charger 121 to the mobile terminal device 101. The charger identification information is stored in a storage unit provided in the charger identification information sending unit 122. The charger identification information may be stored in another storage unit (not shown) and extracted and sent by the charger identification information sending unit 122.
When the mobile terminal device 101 is connected to the charger 121 to charge the rechargeable battery 102, the charger identification information sending unit 122 sends the charger identification information to the mobile terminal device 101. The sent charger identification information is received by the charger identification information reception unit 103. When the charger identification information reception unit 103 receives the charger identification information, the setting information extraction unit 105 extracts, from the setting information storage unit 104, setting information corresponding to the received charger identification information. When the setting information is thus extracted, the setting unit 106 sets the extracted setting information in the mobile terminal device 101.
As described above, in this exemplary embodiment, setting information corresponding to charger identification information sent from the charger 121 is set in the mobile terminal device 101. Hence, according to this exemplary embodiment, constructing setting information in accordance with the use situation in the place where the charger 121 is provided makes it possible to more properly change a function in accordance with the use situation.
For example, consider a case in which the mobile terminal device is wirelessly connected outdoors to a base station operated by the carrier in use, whereas the device is connected to a femtocell and then to a network at home. In this case, when charged by the charger 121 arranged at home, the mobile terminal device receives the charger identification information from the charger 121 so that setting information to connect the femtocell can be set in the mobile terminal device 101. In this case, the setting information to connect the femtocell is stored in the setting information storage unit 104 in correspondence with the charger identification information.
In the area where the charger 121 is arranged, the cellular phone may need to be set in the silent mode. In this case, the mobile terminal device receives the charger identification information from the charger 121 so that setting information to set the silent mode can be set in the mobile terminal device 101. In this case, the setting information to set the silent mode is stored in the setting information storage unit 104 in correspondence with the charger identification information. In the area where the charger 121 is arranged, the use of the camera function, the word processor function, the recording function, the music playback function, the TV reception function, and the like of the mobile terminal device 101 may be restricted. In this case, the mobile terminal device receives the charger identification information from the charger 121 so that function restriction setting information to restrict the functions can be set in the mobile terminal device 101.
In the above-described exemplary embodiment, the charger identification information is provided for an individual charger so as to enable identification (discrimination) of each charger. However, the present invention is not limited to this. The charger identification information need only allow to identify, for example, the area where the charger is arranged. Single charger identification information may commonly be provided for a plurality of chargers arranged in the area where a function as described above is to be set.
The second exemplary embodiment of the present invention will be described next with reference to
The mobile terminal device 201 is, for example, a general cellular phone that is currently commercially available, and includes a rechargeable battery 202 formed from a secondary battery such as a well-known lithium ion battery. Although not illustrated, the mobile terminal device 201 also includes an antenna, a transmitting/receiving unit, a main control unit, an operation unit, a storage unit, and a display unit, and is connectable to various kinds of networks.
The mobile terminal device 201 also includes a charging monitoring unit 203 that detects supply of charging power (applying a charging voltage) supplied from the charger 221 connected to charge the rechargeable battery 202. The mobile terminal device 201 also includes a charger identification information request unit 204 that requests the charger 221 to send charger identification information to be used to identify the charger 221 when the charging monitoring unit 203 detects applying the charging voltage. The mobile terminal device 201 also includes a charger identification information reception unit 205 that receives the charger identification information from the charger 221 after the charger identification information request unit 204 has sent the request. The mobile terminal device 201 also includes a setting information storage unit 206 that stores setting information associated with the charger identification information. The mobile terminal device 201 also includes a setting information extraction unit 207 that extracts, from the setting information storage unit 206, the setting information corresponding to the charger identification information received by the charger identification information reception unit 205. The mobile terminal device 201 also includes a setting unit 208 that sets, in the mobile terminal device 201, the setting information extracted by the setting information extraction unit 207.
On the other hand, the charger 221 includes a charging unit 222 that supplies charging power to the mobile terminal device 201. The charger 221 also includes a charger identification information request reception unit 223 that receives the charger identification information sending request from the mobile terminal device 201. The charger 221 also includes a charger identification information sending unit 224 that sends the requested charger identification information to the mobile terminal device 201 when the charger identification information request reception unit 223 has received the sending request.
In this exemplary embodiment, as shown in
For example, assume that the setting information for network connection via the femtocell 303 is not stored in the setting information storage unit 206 in correspondence with the charger identification information to be used to identify the charger 221. In this state, the user performs the operation of doing the settings for network connection via the femtocell 303 in the mobile terminal device 201 at home. In the state in which the settings have thus been changed, the mobile terminal device 201 is connected to the charger 221 to perform charging. Then, the charger identification information sending unit 224 sends the charger identification information in response to the request from the charger identification information request unit 204, and the charger identification information reception unit 205 receives the charger identification information.
Upon receiving the charger identification information, the setting information extraction unit 207 searches the setting information storage unit 206 for the setting information corresponding to the charger identification information. Since the setting information associated with the charger identification information is not stored in the setting information storage unit 206, as described above, the setting information extraction unit 207 determines that the setting information corresponding to the charger identification information does not exist. When the determination is done, the setting unit 208 stores the setting information for network connection via the femtocell 303, which is currently set in the mobile terminal device 201 as described above, in the setting information storage unit 206 in correspondence with the received charger identification information.
The setting information storage unit 206 thus stores the setting information for network connection via the femtocell 303, which is associated with the charger identification information. From then on, when charging is performed by connecting the charger 221, the setting information for network connection via the femtocell 303 is set in the mobile terminal device 201.
The operation of the charging system including the mobile terminal device 201 and the charger 221 according to this exemplary embodiment will be explained below with reference to the flowchart of
When the charging monitoring unit 203 detects applying the charging voltage supplied from the charger 221 in step S401, the charger identification information request unit 204 requests the charger 221 to send charger identification information to be used to identify the charger 221 in step S402. After that, the charger identification information reception unit 205 waits for reception of the charger identification information sent from the charger 221 (charger identification information sending unit 224) for a set time (steps S403 and S404).
When the charger identification information reception unit 205 receives the charger identification information (Y in step S403), the setting information extraction unit 207 searches the setting information storage unit 206 for the setting information corresponding to the received charger identification information. If the setting information corresponding to the charger identification information is found by this search (Y in step S406), the setting unit 208 sets the extracted setting information in the mobile terminal device 201 to change its settings (step S407).
On the other hand, if the setting information corresponding to the charger identification information is not stored in the setting information storage unit 206 (N in step S406), the setting unit 208 stores the set state of the mobile terminal device 201 at the point of time the charger identification information has been received in the setting information storage unit 206 in association with the received charger identification information. Note that if the set time has elapsed in the time elapse determination of step S404, the operation ends without performing the above-described processing from step S405.
In the above-described exemplary embodiment, the setting information corresponding to the charger identification information sent from the charger 221 is set in the mobile terminal device 201. As a result, according to this exemplary embodiment, constructing setting information in accordance with the use situation in the place where the charger 221 is provided makes it possible to more properly change a function in accordance with the use situation. In addition, since the setting information can include the settings of the variety of functions of the mobile terminal device, complex settings for a combination of the functions can easily be changed.
Note that the present invention is not limited to the above-described exemplary embodiments, and many modifications and combinations can occur to those who have normal knowledge in this field without departing from the technical scope of the present invention. For example, the mobile terminal device may have network access functions for wireless LAN, WiMAX, and the like, and the settings of these functions may be stored as setting information. The address information of a connection destination access point, a server, or the like may be stored as setting information. A combination of a plurality of pieces of charger identification information and setting information may be stored. A desired combination of charger identification information and setting information may be erasable by the user operation.
The charging unit and the charger identification information sending unit may be combined as separate devices. For example, the charger identification information sending unit may separately be mounted on a charging stand including the charging unit. The charger identification information may be sent using a dedicated signal line different from the power line for the supplied charging. The charger identification information may be superimposed on the charging power (voltage signal supplied from the charger for charging). Alternatively, the charger identification information may be sent using a wireless medium such as NFC (Near Field Communication).
Some or all of the above-described exemplary embodiments can also be described as in the following supplementary notes but are not limited to the followings.
